You can already have most of that with existing features around smart collections or publishing collections.
Actor collections → smart collection based on an advanced filter by actor
Universe collections → that’s more or less possible manually or based on some filter criteria (e.g. smart collection based on advanced filter Studio=Marvel Studios).
Seasonal Collections → this one is probably the trickiest of your suggestions – you can currently only cover this with manually assigned collections
Smart Collections → there’s already a few suggestion for that…
I’m aware of all this but having over 100 collections it gets hard to find. What I mean is tabbed collections so you have film collections on the left then within that you have the collections I suggested across the top.
